Polymorphism is taken from the greek word which means "many
forms"...
So polymorphism means "to carry out operations of
different processing steps by function having same
messages".
when a base class member function can be overridden by
defining a derived class member function with same name as
that of the base class member function,then such type of
concept is called "Polymorphism".(one interface multiple
methods)
polymorphism is of two types- compile time(early or static
binding) and run time(dynamic or late binding)..
in comlite time is of two types-function overloading and
operator overloading.
in run time is of two types-virtual function and pure
virtual function..
